skirt hat boots dress Demi Lovato tattoo sad

Oh my goth!

Demi Lovato must be having one of those days because she stepped out in head-to-toe black, while on a trip to Nine Zero One Salon in Beverly Hills, on Wednesday.

The Skyscraper singer was looking a bit down, but she has lots to celebrate. Lovato turns 19 on Saturday, and she's planning quite the exclusive party.

The Camp Rock star is reportedly pulling out all the stops and will be throwing a joint birthday party with her friend and stylist, Hanna Beth, at a top-secret location next week.

Apparently the BFFs are also having custom dresses made for the big day -- let's hope Demi picks something a bit more cheery than what she's got on here!
